Title: Gear pump
Inventor: AIMURA HISAO
IPC: F04C2/12
Filed: 1982-06-23
Abstract: PURPOSE:To increase durability of a gear pump, by preventing contact of a driving gear and a driven gear at or near the tooth end corner parts of the gears and thereby preventing seizure or wear of them by making the gears from a ceramics material and applying crowning to them. CONSTITUTION:A driving gear 6 and a driven gear 8 are made of alumina or a ceramics material such as silicon nitride and crowning is applied to them. That is, the tooth thickness of the gears 6, 8 is reduced gradually at the opposite end parts in the direction of the face width of the gears so that they are not brought into contact with each other at said parts. With such an arrangement, it is enabled to prevent breaking of the gear teeth at their tooth end corner parts 15 that has been caused by the impulsive load acted to the gears during operation of a pump. Thus, since seizure at the sliding surfaces or early wear of gears is not caused even if the gear pump is used for a fluid having a low viscosity such as water, warm water or a solvent.

Abstract: PURPOSE:To allow the setting of many types of eccentricity by providing a reference stopper on a fixing member which is located on the opposite side in a slide direction of a screw shaft of a slider. CONSTITUTION:When the drive shaft 38 of a nut liner 37 is engaged with a screw shaft 35 to make positive rotation of the liner 37 for sliding a slider 4 to a D1 direction, the end face 40a of the stopper 40 of the slider 4 is pressed against the end face 41a of the reference stopper 41 of a fixing member 7 as shown by broken lines, so that the rotation resistance of the liner 37 is detected by a control device 39 to stop the rotation of the liner 37 for stopping the slider 4. The position of eccentricity (S) to the rotation center line l2 of a main axis 2 is acknowledged as an initial position by the control device 39. The slider 4 is then slided to a D2 direction by the reverse rotation of the liner 37 so that the eccentricity (d) of the slider 4 to the rotation center line l2 of the main shaft 2 is moved DELTAX more than the eccentricity (d1), and then returned the extra distance DELTAX to a D1 direction, where the slider 4 is clamped.

Title: Character pattern data storage device and data compressing and storing method
Inventor: SATO FUMITAKA
IPC: G09G5/24
Filed: 1992-04-28
Abstract: PURPOSE:To raise the compression rate of character pattern data to be stored by compressing data of different parts at the time of storing shapes of characters consisting of left-hand radicals or right-hand radicals whose size and shapes are approximately equal to one another but details are slightly different from one another. CONSTITUTION:A CPU 1 reads out pattern data of a character to be printed from a ROM 2 and gives it to a character pattern generating circuit 3. Character pattern data may consist of pattern data peculiar to the character, pattern data of a common part like a right-hand or left-hand radical, and data of the difference from pattern data of the common part, and the character pattern generating circuit 3 draws the outline of the character in an SRAM 4 in accordance with these pattern data. The CPU 1 transfers the outline of the character in the SRAM 4 onto a bit map memory 5 while painting out the inside of this outline. A printer control part 6 sends character data on the bit map memory 5 to a printer device 7 to print it. Difference data is used to reduce the storage volume of character pattern data in the ROM 2.

Title: Fast breeder reactor plant
Inventor: OTA SHUICHI
IPC: G21C1/02
Filed: 1987-05-07
Abstract: PURPOSE:To reduce the number of the heat shield plates above a cold pool to a large extent, by arranging a double partition wall isolating a reactor core in a reaction vessel main body and arranging a separation type intermediate heat exchanger in the double partition wall. CONSTITUTION:This plant is constituted so that a reactor core 2 and a primary cooling material 3 are received in a reactor vessel main body 1 and the circumference of the reactor core 2 is surrounded by a cylindrical partition wall 4. The primary cooling water 3 heated by the reactor core 2 enters from the inlet 11 provided to the inside partition wall 4a of a double partition wall 4 to be subjected to the heat exchange with the secondary cooling material of an intermediate heat exchanger 8. The primary cooling material cooled through the heat exchange flows in a cold pool from the outlet 12 provided to the outside partition wall 4b of the double partition wall 4 to be again sucked by a recirculation pump 7. In this case, since the heat shield plates necessary for being arranged to the whole of the under surface of a roof slab heretofore may be arranged only to the under surface of the hot plate corresponding to the inner cylinder of the double cylinder in a multiple structure, the number of the heat shield plates above the cold pool can be reduced to a large extent.

Title: Setting guard device for system parameter
Inventor: UNO TOSHIYUKI
IPC: G05B9/02
Filed: 1986-05-14
Abstract: PURPOSE:To prevent I/O devices from developing malfunction by storing information of high importance and information of less importance separately in a memory for system parametersfor storing of information for I/O devices, and by providing a switch which invalidates the address designation for address area of information of higher importance. CONSTITUTION:System parameter [28]-[2F] of higher importance are housed in an address area where the MSB of the address of a memory 2 for system parameter comes to '1'. If a hidden switch 6 is closed at the time of writing and if the MSB of the address is '1', a gate circuit 7 invalidates a writing in the memory 2 for system parameters. Therefore an illegal operation can be prevented. By reporting the state of the hidden switch 6 to a control part 1, and deciding whether the error of a memory access comes from a reading error or an error due to an invalid switch, it is possible to improve the retention and reliability of parameter information.
